Oversampled sigma-delta D/A converters and fixed-point sample rate converters can add significant amounts of distortion when playing CD-format recordings. This distortion is caused by intersample musical peaks that overload our digital playback systems. These overloads often occur many times per second, even in a well-recorded track.

This distortion can reach high amplitudes, and it can easily be measured, but it is completely invisible to traditional audio measurements. This distortion can easily be eliminated from our playback hardware, but most of the audio industry has failed to recognize this issue.

Intersample clipping may be the single most audible defect in fixed-point PCM playback systems. It is the elephant in the room.

We need to change the way we build and test our digital playback systems.  Discover The Solution...

An Introduction to Benchmark

John Siau, VP and Director of Engineering, gives us an overview of his company, their design philosophy, and the pioneering products Benchmark offers for high-performance audio.

Benchmark Media, founded in 1983, has a rich history of innovation in the audio industry. Initially specializing in broadcast equipment, the company transitioned to high-end audio products in the early 2000s. Their commitment to engineering excellence has resulted in numerous accolades and a reputation for creating some of the most accurate and reliable audio equipment available.

John discusses some of Benchmark's key products, including the AHB2 power amplifier, LA4 preamp, DAC3, HPA4 headphone amp, and Studio&Stage(TM) audio cables. These products exemplify Benchmark's dedication to pushing the boundaries of audio performance, making them a favorite among audiophiles and professionals alike.

The Benchmark Product Line

Benchmark manufactures DACs, preamplifiers and power amplifiers. This video explains the various models and recommends several different system configurations. It also explains the upgrade path if you wish to incrementally build the ultimate benchmark system.

Made in USA

Designed, assembled and tested in Syracuse, NY, USA.

The DAC3 HGC is Benchmark's top-of-the-line digital to analog converter. Benchmark's DAC1, DAC2 and DAC3 converters can be found in many of the finest recording studios. When added to a home hi-fi system, Benchmark DACs are the fist step in building a studio-quality signal chain.

Our products bring the studio experience to your listening room.  

Get the most out of your Benchmark DAC!

There are some hidden features in the Benchmark DAC2 and DAC3 that can be enabled by moving some of the internal jumpers.

• Change the XLR Output Level
• Adapt the Headphone Gain to Match your Headphones
• Disable the Headphone Mute Switch

If you are using a separate preamplifier with your Benchmark DAC, then this video is for you!

Benchmark DACs Can Be Used With or Without a Separate Preamplifier

Most Benchmark DACs include preamplifier functions such as a volume control and audio input selection. These DACs are designed to directly drive virtually any audio power amplifier without the need for a separate preamplifier.

Nevertheless, if you chose to add an external preamplifier, you will want to change some of the programable features in your Benchmark DAC.

Learn How to Enable the Preamplifier Compatibility Functions in Your Benchmark DAC

All Benchmark DACs include special functions to make it easy to integrate a separate preamplifier. The DAC volume control, DIM function, and MUTE function can be bypassed collectively or individually, according to the needs of your system.
